Leaks behind siding are hard to spot until damage shows up inside. By then, framing and sheathing are often already affected. In Toledo, Sylvania, and Maumee homes, this is commonly caused by improper flashing or aging materials.
Hidden Siding Leak & Structural Repair
"I had a moldy smell in my bedroom and staining on the interior wall near the ceiling. A siding company came out and said I needed new siding. $11,000. They replaced the entire side of the house.
Four months later, after a heavy rain, the stain came back. The smell got worse. I called them back. They said, 'Must be a roof issue' and left.
A friend in Oregon OH used you for a water problem and gave me your number. You pulled off a section of the new siding and showed me the problem — no flashing around the window above. Water had been running down behind the siding for years. The sheathing was rotted. The studs were wet.
You removed the damaged structure, installed proper flashing, replaced the framing, and rebuilt it correctly. The siding company never even checked behind the old siding before covering it up with new material.
I spent $11,000 with them. I should've hired someone who fixes water problems — not just covers them."
Why Siding-Only Repairs Fail
Replacing siding without addressing flashing and water paths usually means the leak continues behind the new material. You end up with brand new siding covering rotted framing.
The Right Way
Find where the water is actually entering. Remove siding where needed. Repair damaged structure. Install proper waterproofing. Then restore siding correctly.
Water marks on walls or ceilings near exterior walls
Materials that feel soft or spongy to the touch
Musty odors that won't go away, especially near exterior walls
Interior paint bubbling or peeling near walls
We trace leak patterns back to the source — windows, flashing, J-channels, trim, or seams.
We don't guess. We open affected areas to see what's actually damaged behind the siding.
Replace rotted sheathing, studs, and any compromised framing. Fix the structure before closing it back up.
Install flashing, housewrap, and sealants correctly. Then reinstall siding so water can't get back in.
